Signet of Binding

With the pve update to Signet of Binding, I had tried out binding a few enemy summoned spirits.

Sunjiang District Mission : Binded spirit of portals (they dun have an expiry time) as long as their HP isn't 0. You can summon spirit them where ever you go in that mission.

Recuperation from enemy side: Seemed bugged, it doesn't gets you the recuperation effect even if you controlled it.

Things left to be tested: The 4 Spirits in Mallyx castle. I am very curious if these 4 spirits if controlled will backfire the effects to mallyx. (cant tried it don't have the other quests cleared) If anyone is keen to try with ur 4 other quests completed please post results here.

If it really backfires effect to Mallyx, it will be fun ~

Might use it on duncan's spirits @ slavers

Would Summon Spirits 'reset' the just-binded enemy spirits like Recuperation etc. to give the effect? I haven't had the time to test this..

I have used the Signet of Binding in Slavers and it is an almost complete bust. It is not usable on enemy Rit spirits at all. I was, however able to use it effectively on enemy Ranger spirits (winnowing, symbosis, etc), but the description says that it is usable on Enemy Spirits...not just some of them...it implies all of them.

Is this a bug?

EDIT---

Summon Spirits worked on my Rit spirits and also on the spirits that I was able to steal from the enemy. They all shadow stepped.

Even in PvP, whenever I vs a rit one on one, I find this to be epic.
